Hello Alice, A single 10 GigE connection should be able to carry two channels of 100 MS/s. Here is a link to some advice for tuning the Ethernet performance of your computer. http://files.ettus.com/manual/page_transport.html Your current program has no use of timed commands so the phase offset wi

Hello Dr Henarejos, The N310 has the same level of RFNoC support as the X310, the same blocks can be used on either. They use a common architecture so the structure and properties are essentially unchanged. The uhd_image_builder is in the process of having N310 support added, that should be releas

Hello Alice, I think you have two different issues. You should not be encountering Late errors. How do you schedule your timed commands? What connection to the host computer are you using? 10 GigE should be able to handle 100 MS/s, are you using 1 GigE? Separately, there will always be a phase of

Hello Lucas, The E310's ethernet connection is directly linked to the ARM side of the processor so it is not possible to directly stream samples to the host. We do have an application note describing how to forward samples to and from a host computer from the E310. https://kb.ettus.com/Streaming_p

Dear all, - Which is the state of development of RFNOC in the new USRP N310? I cannot find any reference to N310 in the RFNOC documentation. - Which is the number of RFNOC blocks available in the N310 images? - Is uhd_image_builder_gui prepared for N310? Regards. -- Dr. Pol Henarejos Researc

Hi all, I have to transmit two flows with the same "start trigger". I used one USRP X300 with two channels, but because of the large bandwidth (100MHz), there is the L error. So, I tried to use two USRPs X300 with the OctoClock, but when I record the transmitted signal they are not synchroni

[USRP-users] Bypass Ettus E310 samples to external host

2018-06-15 Thread Lucas Val TerrĂ³n via USRP-users
Hello all, I am wondering if there is any way tested to transmit samples from Ettus E310 to an external host to process them. Two options in mind: 1. Transmit samples by Ethernet interface. 2. Bypass samples directly from the FPGA. Thanks. ___ U
